Adhesion Promoter 111, Clear, 250 mL Bottle, 4 per case

Somehow this product makes sticky stuff stick better to many surfaces. Not certain how it works, as it doesn't leave any kind of residue that you can see or feel, and just evaporates very quickly. I suspect it penetrates the material very slightly or perhaps just leaves a layer a few molecules thick.

Excellent product. I use it anytime I need to mount something. I wish I knew about this years ago. This bottle is a much better value than the single use wipes. I think this will out live me

This stuff works!!!!!

I have a Tesla Y dual motor long distance. I have added all sorts of "enhancements" to offset the cheap design shortages - movable screen, splash guards, cockpit enhancements, top-of-steering stalk charger, rear LED lights for rear tow patch section and other rear lights (which has saved me from one rear-end collision due to bright attention-grabbing strobe effect I am sure - the guy behind me pulled into the left-turn lane beside me and we met eyes). I installed a set of the neoprene gaskets to reduce dirt penetration and noise but the attachment failed in many places. I ordered this product, and spent a lot of time using goof-off to remove every bit of old neoprene. I then used 99% ethyl alcohol to remove all residue of the goof-off.. I then liberally used this product to coat the metal of the Tesla where the new neoprene gaskets were to fit, and I went wider just in case. After several weeks I can confirm that the new neoprene is holding fast just as it should, thanks to this adherent. Many suppliers give little pledgets like alcohol swabs of this 3M solvent chemical - buying this is far better value if you are serious about making an install bulletproof. I recommend this product and would buy it again. Oh, and yes, the Tesla has been even more quiet as a result. Even if you don't have a T you would be good to use this to apply any neoprene gaskets in any vehicle, or doors of your house, or window gasketing of neoprene material.

Great stuff I used it to attach some fender flares to my offroad rig, cleaned both surfaces (fender flare and body planes) sandwiching a 3M double adhesive tape and they're are glued there, not even mud, heavy rain or rocks have made flimsy. Definetly will use whenever working with double adhesive tape
